ALL PERSONS traveling by air outside of the United States are required to present a passport or other valid travel document to enter or re-enter the United States.
LAND AND SEA TRAVEL
The following summarizes information available on the Department of Homeland Security’s website.
U.S. citizens need to present either (a) a passport, passport card (available in spring 2008), or WHTI-compliant document; or (b) a government-issued photo ID, such as a driver’s license, along with proof of citizenship, such as a birth certificate.
As early as June 1, 2009, the U.S. government will implement the full requirements of the land and sea phase of WHTI. The proposed rules require most U.S. citizens entering the United States at sea or land ports of entry to have a passport, passport card, or WHTI-compliant document.
Note: The passport requirement does NOT apply to U.S. citizens traveling to or returning directly from a U.S. territory.
U.S. PASSPORT AND WHTI COMPLIANT DOCUMENTS:
U.S. Passport: U.S. citizens may present a valid U.S. passport when traveling via air, land or sea between the U.S. and the aforementioned Western Hemisphere countries.
The Passport Card: U.S. citizens may begin applying in advance for this new, limited-use, wallet-size passport card beginning February 1, 2008. We expect cards will be available and mailed to applicants in spring 2008. When available it will only be valid for land and sea travel between the U.S. and Canada, Mexico, the Caribbean region, and Bermuda.
